On the OMAP AM3517 platform the uart4_ick gets registered

This solves the following oops:

[] Unhandled fault: external abort on non-linefetch (0x1028) at 0xfa09e008
[] PC is at serial_omap_pm+0x48/0x15c
[] LR is at _raw_spin_unlock_irqrestore+0x30/0x5c

Which patch broke this? Adding a Fixes: line will help us figure
out where to backport this.


The issue has been around since the legacy clock data code already, I am not quite sure which initially broke it though. As such, we can use the initial clock conversion commit as a fixes by for this:

commit aafd900cab87d339dc3004c241eebc854005124b

    CLK: TI: add omap3 clock init file

I'll add a fixes tag to this and queue it for 4.3-rc-fixes.
